FLUID-OPERABLE MECHANISM.

To all 'u'hom it may concern 1 Be it known that we, REYNOLD JANNEY andHARVEY D. \VILLIAMS, citizensof the United States, residing at New .Yorkand Wallingford, respectively, in the counties of New York and NewHaven, States of New York and Connecticut, have invented certain new anduseful Improvements in Fluid-Operable Mechanism, of which the following'isa specification.

This invention relates to What we will for convenience termfluid-operable mechanism.

In various arts there are found an oscillatory member and connectingrods jointed to the oscillatory Inember'at opposite sides of the axis ofoscillation thereof.

It is the primary'purpose of our invention to provide mechanism which ispreferably fluid governed in character and is so related with theconnecting rods as to operate them and simultaneously automaticallycompensate for changes in obliquity of said connecting rods.

. venient forms of embodiment of the invention which to enable thoseskilled in the art to practise the same Willbe set forth fully in thefollowing description. We do not, however, restrict ourselves to thisparticular showing; we may depart therefrom in several respects withinthe scope of the inventioncovered by the claims following saiddescription.

Referring to said drawings; Figure 1 is a top plan view offluid-operable mechanism involving our invention. Fig. 2 is a sideelevation of the same. Fig. 3 is a transverse section on the line33 ofFig. 2 looking in the direction of the arrow; Figs. 4 and5 areperspective views on enlarged scales of a yoke and a piston constitutingparts of the mechanism.

Like characters refer to throughout the several figures.

As already noted mechanism involving our invention can be employed inwidely' different fields; that is to say, the oscillatory member towhich We have referred may subserve any desired function. Suchan'oscillatory member as suits our conditions, is that Specification ofLetters Patent.

denoted in a general way by 2, and it will be assumed that saidoscillatory member" is a rudder head which after the usual fashion maybe rigidly connected with the post 3. Pivoted or otherwise suitablyconnected with the oscillatory member 2 at opposite sides of its axisofmotion are the connecting rods 4 and 5, the points of connection ofthese rods or links 4 and 5 with the oscillatory member 2 beingpreferably at equal distances from said axis. The two rods are connectedat their forward ends as will heremafter appear, with elements whichmove in straight pathsand these elements form part of a floatingfluid-operable mechanism which s of such nature thatwhen eitherconnecting rod lS\ imparted a thrust, a pull of exactly equal extent isgiventhe other by said mechanism.

As shown'the rod or link 4 is pivoted as .at at its forward end in theslot 7 of the -lug8 pro ecting laterally from the piston 9, the terminalportions of which reciprocate in the duplicate cylinders 10 and I1mounted for bodily reciprocatory move ment in the pillow blocks 12 and13 rising from the base or bed 1 1. The two cylinders 10 and 11 as shownare cqnnected by the yoke 15 and also by-the tie rods or bolts 16 whichextend, through abutting flanges on the yoke, and cylindersrespectively. The

lug 8 to which we have'referred, extends through the opening 17'of, theyoke 15 or the part 15 might be considered as a tube having an openingin one side through which said lug or projection 8 extends. 'The yoke 15on the side thereof opposite that having the slot or opening 17 isfurnished with an outward projection 18 slotted to receive the forwardend of the connecting rod 5 pivoted to said projection 18 as by thepivot 19. The reciprocatory. mounting of the two cylinders and pistonwith the rods connected -with the cylinder and piston mechanismsrespectively compensates for variations in obliquity of the twoconnecting rods or links as they are oscillated and not only is'this sobut the pull applied to either rod exactly equals the thrust exerted onthe other. The two projections and lugs 8 and l8 have a bearing upon thebase or bed 14, the latter having parallel ways or ribs 20 flat on theirupper sides to receive the correspondingly flattened surfaces on y theunder side of the two lugs or projections 8 and 18. The piston 9 alsohas a bearing engagement against the connecting yoke 15, the two partshaving flat engaging surfaces 21 for such purpose. It, therefore,follows that as the 'two coaxial cylinders and the piston move backwardand forward, there is no possibility of their turning. This, of course,is merely one of severaladvantageous ways of preventing rocking or movement of the two cylinders and their cooperative piston about theirlongitudinal axes.

The power for reciprocating the piston 9 may be supplied in anydesirable manner,

for instance by the hydraulic variable pump 22 which may be constructedexactly like the pump or so-called A-end of .the yariable, speedgearshown in I Aetters Patent N Q 924,787 granted to Bfnold Janney,-June ,15, 1909, and to whieit'referepce may be,had. This pumpoperating motor as 23 may be edfiir-any desirable manner. As shown'thepump and its motor-0f electric type, are both rigidly mounted on theyoke 15, but this as will be inferred, is not a matter of necessity. 1After the usual fashion the electric motor 23 is coupled to the shaft ofthe hydraulic pu mpf2 2, the latter being provided with a regulator suchas the well-known tilting box operable by the shaft 24 which can beactuated directly by' hand, by power or otherwise From the pump thepipes 25 and 26 extend, the pipe 25- being connected with the cylinder10, hile the pipe 26 is connected with the cylinder 11. The two pipesare intersected by a safety valve 27 of ordinary kind and which alsoacts as a by-passafter the usual fashion. Through theoperation of thecontrol shaft 24, fluid can edirected in alternation into the cylinders11 a d 12 so as to effect the relative operation 0 the piston 9 andconnected cylinders lOand 11 and thereby apply a thrust to one of thetwo connecting rodsl and 5 and a pullon the other in accordance with thecylinders 10 and 11 into which the liquid is initially pumped by thepump 22. What we claim is:

1. The combination of piston mechanism and cylinder mechanism bothmounted for relative reciprocatory movement, an oscillatory member, rodsconnected with the oscillatory member at opposite sides of its center ofmotion, one rod being connected with the piston mechanism and the otherwith the cylinder mechanism, and means for relatively operating thepiston and cylinder mechanisms.

The combination of piston mechanism and cylinder mechanism, anoscillatory member, rods connected with the oscillatory member atopposite sides of the center of motion, one rod being connected with thepiston mechanism andtlie other with the cylinder mechanism, and meansfor relatively operating the piston and the cylinder mechanisms. 1
